Crazed Times Square stabber’s brother reveals mom of three’s longtime struggle with mental health, possible bipolar diagnosis

The crazed knife-wielding woman who went on a sudden stabbing rampage near Times Square — before being shot dead by police — was a mother of three who long struggled with her mental health and had multiple erratic run-ins with police, her family and sources revealed Tuesday.

Pamela Cisneros, 49, battled what her stunned brother described as bipolar disorder, but had been getting treatment in recent years — and showed no sign she’d go murderously berserk as she did during terrifying random attacks Monday, he said.

“She never showed any aggressiveness or being violent. I don’t know what happened,” Patrick Peralta, 59, told The Post, adding his sister, a Queens native, had found some stability through medication in recent years and reported feeling “fine” as recently as Saturday.

Court records, meandering social media posts, neighbors and sources paint a portrait of Cisneros living an alternately troubled and tranquil life before she chillingly snapped in the heart of Manhattan — slaying a young Bank of America executive and injuring a Rhode Island man who was in town visiting his son.
